Change processor quantums to tweak application priority

When running several applications/processes simultaneously then a coordinator/scheduler is needed to make sure that all applications get a fair quantum/slice of the CPU time. The coordinator can be configured in how it gives CPU quantums to the different applications running.

Foreground vs. Background:
Foreground boost means that the application currently having focus will get more quantums than other applications, thus it will not be disturbed that much by background processes.
Background means that all applications gets equal amount of CPU quantums.

Short vs. Long (Win2k+):
Short quantums means that applications can hold the CPU for a short time, thus giving smooth multitasking.
Long quantums means that applications can hold the CPU for longer time, thus spending less time on process switching.

Variable vs. Fixed (Win2k+):
Variable quantums means that the foreground application can hold the CPU for a longer time.
Fixed quantums means that the CPU time within a quantum is the same for all applications (Though some applications can get more quantums than others).
